Analysis and simulation of the proactive hybrid circuit breaker
2015 IEEE 11th International Conference on Power Electronics and Drive Systems, 2015 High Voltage Direct Current (HVDC) short circuitprotection is a fundamental requirement for any HVDCtransmission system. Presently, all point-to-point links areprotected using circuit breakers on the AC side of theconverters. In order to enable HVDC grids, a more advancedprotection system must be developed. HVDC circuit breakersare one solution for the

Dual-circuit hybrid circuit breaker
2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017 A DC fault will propagate quickly in a DC grid and results in significant DC voltage drop and large current increase. To protect the DC grid from the DC faults, the concept of hybrid HVDC circuit breaker (DCCB) is widely-accepted due to its low conducting loss and fast operation speed.

Experimental tests on a superconducting hybrid DC circuit breaker [PDF]
, 2016 Direct Current (DC) transmission systems are widely recognized offering significant potential for long distance high power delivery. DC circuit breakers are a key enabling technology for managing faults in multi-terminal DC networks (MTDC). However, DC current breaking is much more challenging than in AC systems because there is no natural zero ...

Hybrid DC circuit breaker with coupled inductor for automatic current commutation [PDF]
International Journal of Electrical Power and Energy Systems, 2020 HVDC transmission systems using voltage source converters (VSC-HVDC) have been identified as an attractive solution for bulk power delivery over long distance. However if DC grids are to be built using this technology, fast DC circuit breakers are needed.

Design of LVDC Bidirectional Hybrid Circuit Breaker
2021 IEEE Fourth International Conference on DC Microgrids (ICDCM), 2021One of the most challenging hindrances to the spread use of the DC grids is their protection devices. Due to the absence of zero crossing, when a fault occurs, arc extinction becomes an issue for the traditional mechanical circuit breakers. Thanks to the recent advances in solid-state circuit breakers, this problem is solved because of the absence of ...

A Bipolar Hybrid Circuit Breaker for Low-Voltage DC Circuits
2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021Presently available dc breakers fall into three categories, mechanical, static, and hybrid dc breakers. With the advent of dc circuits, generation, and loads, dc breakers are required for system protection. This paper proposes a new alternate method to break dc currents for low-voltage applications.
